CH E3 (CHEVRON SINGLE ACTION PISTONSEAL)

product

CH E3 is a single acting three part Chevron Set which consists of a cotton fabric reinforced bottom ring (BP), a rubber washer (VR) and a pom support ring (AT).

PRODUCT ADVANTAGES:

  • Functions even with poor surfaces
  • Easy installation
  • Adjustable seal housing height due to the reason of being used in open grooves.

APPLICATION:

Used especially in hard working conditions such as iron and steel industry , mining equipment , marine hydraulics , scrap cutters and special cylinders where the actual conditions are difficult to predict

INSTALLATION:

Suitable for open enclosures. If the enclosure height is too tight CH loses its flexibility and therefore increased wear and friction. If'm assembly tools are used the mounting area should not have any sharp edges. Before mounting the CH E3, part by part to be lubricated with oil system.

NOTES: for special applications that require high temperatures , our seal set is being manufactured with reinforced cotton fabric with FPM and special mixture of PTFE backup ring. Additional middle rings can be used depending on the application

MATERIAL: POM / NBR FABRIC
